ANTIIRATTLIN-G MECHANISM roe wrix'rnows.

I j Applicationfiled' April 26, i922. Serial Nd, 556,595.

To all whom it may concern:

Be it known that I, EDWARD EDWARD RICHARDSON, a citizen of the UnitedStates, residing at Maumee, in -the county of Lucas and State of Ohio,have invented certain new and usefullmprovements inAnti- RattlingMechanisms. for Windows, of

cise', and exact description of my invention,

such as will enableothersskilled in the art to which it appertains tomake and use the same. i I

to I such device as will prevent the unpleasant rattling of glass"windows of enclosed automobiles, although my invention is not limited tosuch a use. 7

An object of my invention is to provide ananti-rattling mechanismadapted to be used to prevent. the vibration of a glass window, such asemployed in enclosed automobiles, by the application.of pressureresiliently applied to the surface of such a window, near the edgethereof.

A further object of my invention is to provide such mechanism as maybesimplc to operate, but which may be capable of applying a considerablepressure, re-

siliently, to the-window pane, and which willbe capable of being; set inoperative condition by a simple single operative n ov'en'ient by theoperator and which when sorset will remain in set' position against theportion of contributing causes which in prior constructions have beeneflected to restore the mechanismto inoperative condition, suchcontributing causes being vi-.

bration caused by rough roads, etc. t

Another object of my invention is to'pro vide an inexpensivelyconstructed mecha: nism of the kind described, made principally of sheetmetal and of very few parts and which may be assembled or disassembledrepeatedly and Without any particular skill on the partof'the assembler.

Another object of my inventionis to provide amechanism asdescribed,which may be easily placed on the casing adjacentthe windowpane and which will remain in operative condition for longperiods oftimewvithout attention, and which will moreover, give a presentableappearance, adding rather than detracting from the appearance of thec arto which it is applied.

Other objects offmy invention and the by reference to the drawingsforming a part of this specification, and inwhich drawifngs Fig. 1 showsan 'elevational view of the .mechanism of my invention in normal, un-

attached, inoperative condition.

Fig. 2 shows an elevational view of the mechanism of Fig. l, the partsbeingin v the mechanism. My invention relates to anti-rattling"mechanisms for, windows,v and particularly to awindow casing adjacent awindo-w ane,

the parts being .111 operatlve ad1usted posi tion to restrain vibrationsof the saidw1n'-- dow pane.

. invention itself will be better understood 'Fig; 5 shows "a top. planview of the mechanism as'shown in F1 4.

Fig. "6 shows a view similar to Fig. 2,'but with the operating lever ofthe mechanism thrownto full operative position.

Referring now to the variousfigures,in

all of which like parts are designated by like referencecharacters, at 1I show the enclosing casing for a mechanismembodying my inventiomsaidcasing having a front outer wall 2,end walls 3 and 4 and portions of endwalls 5 and 6. The side of the casing opposite the wall 2 being leftopen as are also portions of the walls 5 and 6 for purposes later to bedescribed.

Thecasing 1 is as'shown formed of sheet metal, the side and end wallsbeing turned up from the outer wall 2 and at right angles thereto, aportion of the wall '5 being omitted so as to provide an opening 7through which the spring vibration subdulng element 8'is adapted topass, portions of the spring 8 occupying different positions through theopening 7 according to the different operative positions of the springand due to the flexing of the spring 8 in the different adjustedpositions thereof. The wall 2 has also a turned up portion9, over whichflange portion 9, a cainming lever 10 fitted, the lever 10 having anopening 11 adapted to encompass the said flange 9,'the

wall 6 base portion omitted from either side oftlie flange 9 for theretaining of the lever 10' and the cam portion 12 thereof, said 'camportion being suitably formed so as to have acamming edge 13, adapted toengage the spring 9. at an intermediate portion 14. The spring 8 isplaced within the frame 1 with its end 15 resting against the wall 5 andthe spring 8 being bent around between the wa ls 5 and 6 and the camsurface 13 of the'lever 1.0 and around a pin 16 secured at its end tothe base 2 the frame 1. The spring 8 thus has anormal tendency tendingto move the soft rubber cap 17 placed on its end away from the pane ofglass shown 18.,The end of the spring 8 is suitably made irregular inshape as indicated in Fig. 3 at 19, and the rubber cap 17 is made ofsuch size that it must be stretched in order to fit over the spring 8.

When the anti -rattling device of my invention is placed in service, itis secured by means of wood screws 20 and 21, passing through openings23 and 24 through the case 1, and into the casing 22 of a window framehaving the window pane shown at 18. Vihen the lever 10 is in inoperableposition as shown at Fig. 2, the cap 17 rests but lightly, if at allagainst the window pane, but when the lever 10 is thrown to the positionindicated in Figs. 4 and (3, the cap 17 is moved against the window pane18 and I exerts a considerable pressure. thereagainst,

the pressure being resiliently applied through the resilience of thematerial of the cap 1? and the spring 8.

The resiliency of the pressure contributes to the prevention of rattlingat all times. and at the same time where a plurality of my improveddevices are in use on different portions of the window panesimultaneously, the window pane will not be placed under such a severeunyielding stress will cause the pane to break when vibrated sharply.

It will be noted also that approximately at the point 25 of the cam face13. the said cam. face surface 18 is disposed further from the center ofrotation of the lever 10. The center of rotation being indicated in Fig.6 by the numeral 27. Therefore. when the lever 10 is thrown to itscompletely operated position the point 25 on the cam face has justpassed that position whee it contacted with the spring 8 and anotherpoint 28 on the said cam face less distant from the center of rotation27 in contact with the spring 8; in other words. the cam is rotated pastthe dead center operative posi- "tion. This contributes towards theperformance of the function of maintaining the lever of set operatedposition under the sustaining pressure of the operated spring 8.

Having thus descr'bed my invention in a specific embodiment, I am awarethat numerous and extensive departures may be made from the embodimentherein illustrated and described, but without departing from the spiritof my invention.

What I claim as my invention is:

1. in a device of the class described, a

substantially open ended rectangular box shaped base member, oppositesides of said boX member having openings therein, a fiat leaf springsecured at one of its ends within the said base member near an endthereof, and having its other end projecting through one of the saidside openings, a camming lever journalled in the said box member andhaving a handle portion projecting through the other said opening, meanswhereby said base member may be secured to the frame of a window withits open cndin contact with my improved devices are in use on differentthe said frame and the end of the said leaf spring adjacentthewindowpane; said camming lever adapted to press the end of the said springfirmly against the window pane when the said handle is operated, and apad of resilient material carried by the said spring end pressed againstthe window pane.

2. In a device of the class described, a base member, a spring striphaving a coiled end removably secured in the said base member and theother end projecting from a side of said base member, a contact pad ofresilient material on the end of the said spring strip, and a camminglever pivotally supported by the said base member and having a cammingface adapted to engage a side of the said spring, said lever whenrotated adapted to cam the said, spring to deflect the same to cause thesaid contact member to exert a yielding pressure against a window pane.
